In this work, graphene oxide was prepared using a modified Hummers’ method and then decorated with nickel using the hydrothermal method. FESEM images of the graphene oxide and graphene oxide-nickel oxide showed that they presented different nanoflake structures. EDX spectra confirmed that oxygen, carbon, and nickel were present in the graphene oxide—nickel oxide. XRD spectra revealed that the crystallinity of the graphene oxide decreased after nickel oxide was added to the system. FESEM images of the nanocomposite polymer showed the morphological changes when graphene oxide and nickel oxide were added to the composite structure. The conductivity results were discussed using a Nyquist plot to confirm the electrical properties of the polymer nanocomposite with the presence of a semicircle and a 45° straight line. The conductivity increased to 1.61 × 10−9 S/m when graphene oxide decorated with nickel oxide was added to the composite system. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
